[0037] Figure 1 It is a schematic side view of the bracket 100 for supporting the photovoltaic module 200 according to an embodiment of the present utility model. The bracket 100 for supporting the photovoltaic module 200 generally may include a plurality of support frame bodies 110, and the support frame bodies 110 are used to be arranged between the support surface 600 and the photovoltaic module 200 to be supported, and are arranged at intervals along the transverse direction of the photovoltaic module 200. And each support frame body 110 includes a first upright post 111 and a second upright post 112, and the first upright post 111 and the second upright post 112 are arranged at intervals along the longitudinal direction of the photovoltaic module 200. The first upright post 111 and the second upright post 112 respectively include a base 111a and a support column 111c. The bottom end of the base 111a is used to connect the support surface 600, and the top end of the support column 111c is used to connect the photovoltaic module 200. And the height of the first upright post 111 is configured to be less than the height of the second upright post 112, so that the photovoltaic module 200 is arranged obliquely along the longitudinal direction of the photovoltaic module 200, so that the photovoltaic module 200 reaches a set light-facing angle. Wherein the support surface 600 can be the ground or the roof 300. Compared with the way of laying the photovoltaic module 200 flat for photovoltaic power generation, after the photovoltaic module 200 is at a certain light-facing angle, the power generation efficiency is higher, and it is not easy to cause dust accumulation, and the operation and maintenance do not need to be frequently cleaned.

[0038] In some embodiments, the photovoltaic module 200 mainly includes a rectangular solar panel 210, and the solar panel 210 is composed of a plurality of solar cell units, and is connected by connecting wires and a circuit board to convert solar energy into electrical energy for output. Figure 1 What is shown in is a side view of the photovoltaic module 200. The longitudinal direction marked in the figure is the length direction of the solar panel 210, and the transverse direction of the photovoltaic module 200 is the width direction of the solar panel 210, that is, the transverse direction is the direction perpendicular to the figure.

[0039] In some embodiments, the support frame body 110 further includes inclined beams 113. The inclined beams 113 are respectively connected to the tops of the first upright column 111 and the second upright column 112, and are connected to the backlight surface of the photovoltaic module 200 to support the photovoltaic module 200 to be inclined. The inclined beams 113 and the first upright column 111 and the second upright column 112 can be respectively connected through triangular connectors 140. The triangular connectors 140 have a stable structure and can bear a large load. Among them, the backlight surface of the photovoltaic module 200 is the side opposite to the light-facing surface, and the light-facing surface of the photovoltaic module 200 is the surface for receiving sunlight. In other embodiments, the inclined beams 113 and the first upright column 111 and the second upright column 112 can also be connected by means of threaded connection or pin connection.

[0040] In some embodiments, the bracket 100 for supporting the photovoltaic module 200 further includes a plurality of cross beams 120. Each cross beam 120 is erected on the inclined beams 113 of a plurality of support frame bodies 110 along the transverse direction of the photovoltaic module 200 and is connected to the inclined beams 113 respectively at positions close to the first upright column 111 or the second upright column 112. Among them, the cross beam 120 and the inclined beam 113 can be connected by means of threaded connection. The plurality of cross beams 120 are connected to the backlight surface of the photovoltaic module 200 to support the photovoltaic module 200 to be inclined. Each cross beam 120 is connected to the inclined beam 113 respectively at positions close to the first upright column 111 or the second upright column 112, which can reduce the bearing pressure of the inclined beam 113. If the cross beam 120 is arranged at a position far from the first upright column 111 or the second upright column 112, it will cause a large bending moment on the inclined beam 113, and the inclined beam 113 needs to have a high bearing capacity.

[0041] Figure 2 is a schematic side view of the bracket 100 for supporting the photovoltaic module 200 according to another embodiment of the present invention, Figure 3 is Figure 2 a schematic partial enlarged view of part A of the bracket 100 for supporting the photovoltaic module 200 shown in another embodiment. In some embodiments, a plurality of pressing blocks 220 are further arranged on the light-facing surface side of the photovoltaic module 200. The plurality of pressing blocks 220 can be evenly arranged along the direction of the cross beam 120, and fastening holes are arranged at the bottom of the pressing blocks 220. The pressing blocks 220 are arranged above the photovoltaic module 200. After the pressing blocks 220 are firmly connected to the cross beam 120 through the fastening holes of the pressing blocks 220 by using fasteners, the pressing blocks 220 can firmly press the photovoltaic module 200 on the cross beam 120, so that the photovoltaic module 200 is stably installed on the bracket 100.

[0042] Figure 4 is a schematic side view of the bracket 100 for supporting the photovoltaic module 200 according to another embodiment of the present invention, Figure 5 is Figure 4Schematic partial enlarged view of the bracket 100 for supporting the photovoltaic module 200 at location B according to another embodiment. In some embodiments, the support frame body 110 further includes a diagonal brace 114. The first end of the diagonal brace 114 is connected to a portion of the diagonal beam 113 between the first column 111 and the second column 112, and the second end is connected to the second column 112. A stable triangular structure can be formed among the diagonal brace 114, the diagonal beam 113, and the second column 112 to enhance the stability of the support frame body 110. Among them, the first end of the diagonal brace 114 and the diagonal beam 113 can be connected through a triangular connector 140, or can be connected by a threaded connection or a pin connection.

[0043] In some embodiments, the bracket 100 for supporting the photovoltaic module 200 further includes a plurality of bottom beams 130. Each bottom beam 130 is laid on the support surface 600 at intervals and is connected to the bottom end of the base 111a to provide support for the support frame body 110.

[0044] In some embodiments, the support frame body 110 further includes a diagonal tension beam 115. The first end of the diagonal tension beam 115 is connected to one end of the second column 112 close to the diagonal beam 113, and the second end of the diagonal beam 113 is connected to the bottom beam 130. A stable triangular structure is formed among the diagonal tension beam 115, the second column 112, and the bottom beam 130, which can enhance the stability of the support frame body 110.

[0045] In some embodiments, the bottom beam 130 is arranged to extend transversely along the photovoltaic module 200. The first columns 111 of a plurality of support frame bodies 110 are respectively connected to the same bottom beam 130, and the second columns 112 are respectively connected to another bottom beam 130, so that the plurality of bottom beams 130 provide stable support for the bracket 100. In other embodiments, the bottom beam 130 is arranged to extend longitudinally along the photovoltaic module 200. The two bases 111a of each support frame body 110 are connected to the same bottom beam 130, so that the bottom beam 130 provides stable support for the support frame body 110.

[0046] In some embodiments, the bracket 100 for supporting the photovoltaic module 200 is arranged on the roof 300. The bottom beam 130 is fixedly connected to the corrugation 400 of the roof 300 through a fixture 150, so that the bracket 100 is fixedly connected to the roof 300, and thus the photovoltaic module 200 can receive sunlight for power generation.

[0047] The types of roofs are diverse, such as flat roofs, pitched roofs, etc. The roofs have different orientations and can be roughly divided into roofs with a north-south orientation and roofs with an east-west orientation. Figure 6It is a schematic side view of a bracket 100 for supporting a photovoltaic module 200 according to an embodiment of the present invention, installed on a north-south slope roof 300. The roof 300 is a pitched roof with two slopes, having a south slope and a north slope, that is, the house runs east-west. The south slope is the slope on the south side, and the north slope is the slope on the north side. The arrow in the figure indicates the south direction. The slope on the left is the south slope, and the slope on the north is the north slope.

[0048] A plurality of groups of brackets 100 for supporting the photovoltaic module 200 are arranged at intervals from south to north on the roof 300 in sequence. It should be noted that, Figure 6 Only a side schematic view of the bracket 100 for supporting the photovoltaic module 200 is shown. The bracket 100 for supporting the photovoltaic module 200 extends along the transverse direction of the photovoltaic module 200, that is, the orientation of the house. Therefore, only one support frame body 110 of the bracket 100 for supporting the photovoltaic module 200 can be seen from the figure.

[0049] In some embodiments, the light-receiving angles of the photovoltaic modules 200 can be adjusted to the same angle so that the photovoltaic modules 200 can all generate electricity with maximum efficiency. Figure 6 Four groups of brackets 100 for supporting the photovoltaic module 200 are sequentially arranged from south to north on the south slope. Since the parameter states adjusted by each group of brackets 100 are the same, the light-receiving angles of the photovoltaic modules 200 on each group of brackets 100 are the same. The parameter state refers to the heights of the first upright post 111 and the second upright post 112. Therefore, the interval distance between two adjacent groups of brackets 100 for supporting the photovoltaic module 200 can be set to be the same, and there is the same shadow control line 500 between two adjacent groups of brackets 100 for supporting the photovoltaic module 200.

[0050] In some embodiments, the interval distance between each group of brackets 100 for supporting the photovoltaic module 200 arranged on the north slope is larger than that on the south slope. This is because the north slope slopes downhill from south to north, and the shadow distance formed after the sun shines on the photovoltaic modules 200 on the north slope is longer. The interval distance between each group of brackets 100 for supporting the photovoltaic module 200 needs to be larger so that each group of photovoltaic modules 200 can receive sufficient light and improve the power generation efficiency.

[0051] Figure 7It is a schematic side view of a bracket 100 for supporting a photovoltaic module 200 according to an embodiment of the present utility model, installed on an east-west sloped roof 300. The roof 300 is a sloped roof with two slopes, running north-south, and the arrow in the figure indicates the south direction. The two slopes of the roof are the east slope and the west slope, and the installation states of the brackets 100 on the east slope and the west slope are the same. A plurality of brackets 100 for supporting the photovoltaic module 200 are arranged at intervals from south to north on the roof in sequence, and the interval distances can be the same, so as to make full use of the roof area to install more photovoltaic modules 200 and improve the overall photovoltaic power generation.

[0052] In some embodiments, a plurality of support frame bodies 110 can be evenly arranged at intervals along the transverse direction of the photovoltaic module 200, that is, each support frame body 110 is arranged at an equal interval distance, so as to provide uniform supporting force for the photovoltaic module 200.

[0053] In other embodiments, there may be different types of solar panels 210 in a group of photovoltaic modules 200. Therefore, a plurality of support frame bodies 110 can be unevenly arranged at intervals along the transverse direction of the photovoltaic module 200. According to the specific size and weight of the photovoltaic module 200, the interval distance between the support frame bodies 110 is reasonably adjusted, so that each support frame body 110 can exert the maximum supporting efficiency and save the number of support frame bodies 110 used.

[0054] In some embodiments, for the bracket 100 for supporting the photovoltaic module 200 installed on the north-south slope, a support frame body 110 can be arranged at intervals of one corrugation 400, and a bottom beam 130 can be correspondingly arranged below the support frame body 110, so that the support frame body 110 is fixedly connected to the bottom beam 130. For the bracket 100 for supporting the photovoltaic module 200 installed on the east-west slope, the distance between two adjacent support frame bodies 110 is not greater than 2 meters, and a fixture 150 is provided between the bottom beam 130 and each corrugation 400 below to ensure that a plurality of support frame bodies 110 can provide stable support for the photovoltaic module 200.

[0055] It should be noted that Figure 7 Only a side schematic view of the bracket 100 for supporting the photovoltaic module 200 is shown. The bracket 100 for supporting the photovoltaic module 200 is arranged along the transverse direction 7 of the photovoltaic module 200. Therefore, only one support frame body 110 of the bracket 100 for supporting the photovoltaic module 200 can be seen from the figure.

[0056] In some embodiments, the orientation of the photovoltaic module 200 can be due south. Because in the Northern Hemisphere, the sun is at its highest at noon in the due south direction. When the photovoltaic module 200 faces due south, it can receive sunlight to the greatest extent, thereby achieving the highest power generation efficiency. In other embodiments, the photovoltaic module 200 can face southeast or southwest. The photovoltaic module 200 with this orientation has the highest power generation efficiency in the morning or evening time periods. Or the photovoltaic module 200 faces east or west. In this case, the photovoltaic module 200 has the highest power generation efficiency in the morning or afternoon. However, due to the relatively small total amount of sunlight in the morning or evening, the overall power generation capacity of the photovoltaic module 200 may be slightly lower than that of the photovoltaic module 200 facing south or southeast / southwest.

[0057] In some embodiments, the sunlight-facing angle of the photovoltaic module 200 located on the north-south slope can be 15 degrees to 25 degrees. Through practical research, when the sunlight-facing angle of the photovoltaic module 200 is adjusted within the above angle range, the power generation efficiency of the photovoltaic module can be significantly improved. Further, the adjustment range of the sunlight-facing angle of the photovoltaic module 200 can be between 18 degrees and 22 degrees, and can be specifically set to 19 degrees, 20 degrees, and 21 degrees. Among them, when the sunlight-facing angle of the photovoltaic module 200 on the north-south slope is adjusted to 20 degrees, the power generation efficiency reaches the highest, which is the best sunlight-facing angle on the north-south slope.

[0058] In other embodiments, the sunlight-facing angle of the photovoltaic module 200 located on the east-west slope can be 10 degrees to 20 degrees. Through practical research, when the sunlight-facing angle of the photovoltaic module 200 located on the east-west slope is adjusted within the above angle range, the power generation efficiency of the photovoltaic module can be significantly improved. Further, the adjustment range of the sunlight-facing angle of the photovoltaic module 200 can be between 13 degrees and 16 degrees, and the power generation efficiency is better, and can be specifically set to 14 degrees and 15 degrees. Among them, when the sunlight-facing angle of the photovoltaic module 200 on the east-west slope is adjusted to 15 degrees, the power generation efficiency reaches the highest, which is the best sunlight-facing angle on the east-west slope. Here, the sunlight-facing angle refers to the angle between the photovoltaic module 200 and the horizontal plane.

[0059] In some embodiments, a part of the column body of the support column 111c of the bracket 100 for supporting the photovoltaic module 200 is disposed in the base 111a, and a plurality of positioning holes 111b are arranged at intervals in the length direction of the support column 111c. The base 111a extends in a direction perpendicular to the support surface 600 and is provided with positioning holes 111b in its length direction. The support column 111c can be pulled out or inserted into the base 111a by a certain distance, and the positioning holes 111b of the base 111a are connected to different positioning holes 111b on the support column 111c by fasteners to adjust the lengths of the first column 111 or the second column 112. In other embodiments, the first column 111 and the second column 112 can also be adjusted in length by using other components such as sliding rails or cylinders that can achieve telescoping or displacement, so that the photovoltaic module 200 is inclined longitudinally along the photovoltaic module 200, so that the photovoltaic module 200 reaches a set light-facing angle.

[0060] Figure 8 FIG. 4 is a schematic view of the installation state of the rear stay bar 160 in the bracket 100 for supporting the photovoltaic module 200 according to an embodiment of the present invention. The bracket 100 for supporting the photovoltaic module 200 may further include a rear stay bar 160. The rear stay bar 160 can be respectively connected to the second columns 112 in two adjacent support frame bodies 110 of the bracket 100 for supporting the photovoltaic module 200 to enhance the stability of the bracket 100 composed of a plurality of support frame bodies 110. Figure 8 FIG. 6 shows a schematic view of the installation of the rear stay bar 160 when the bracket 100 for supporting the photovoltaic module 200 is arranged on a north-south slope. The bottom is the support surface 600. One end of the inclined rear stay bar 160 is connected to the upper edge of a second column 112, and the other end of the rear stay bar 160 is connected to the lower edge of the adjacent second column 112. An approximately triangular structure is formed among the rear stay bar 160, the second column 112, and the support surface 600, which can make the entire bracket 100 more stable.

[0061] Figure 9 FIG. 10 is a schematic view of the installation state of the rear stay bar 160 in the bracket 100 for supporting the photovoltaic module 200 according to another embodiment of the present invention. Figure 9 FIG. 12 shows a schematic view of the reinforcement state of the rear stay bar for the bracket 100 located on an east-west slope. The bottom is the support surface 600. One end of the inclined rear stay bar 160 is connected to the upper edge of a second column 112, and the other end of the rear stay bar 160 is connected to the lower edge of the adjacent second column 112. An approximately triangular structure is formed among the rear stay bar 160, the second column 112, and the support surface 600, which can make the entire bracket 100 more stable.

[0062] In some embodiments, the bracket 100 for supporting the photovoltaic module 200 disposed on the north-south slope or the east-west slope, in which a back tie rod 160 must be provided between two adjacent support frame bodies 110 located at the two side edges, for example Figure 8 and Figure 9 a back tie rod 160 is provided between the two leftmost adjacent support frame bodies 110 and the two rightmost adjacent support frame bodies 110. Since the bracket 100 for supporting the photovoltaic module 200 is used in an outdoor environment, the bracket 100 often needs to face complex and harsh natural environments, and the bracket 100 must be able to resist strong winds of a certain level to ensure that the photovoltaic module 200 is not damaged. And the support frame bodies 110 located at the two side edges are located on the outermost sides of the entire bracket 100 and will be subjected to stronger impacts of strong winds. Therefore, it is particularly necessary to use the back tie rod 160 to reinforce the two adjacent support frame bodies 110 located at the two side edges.

[0063] In some embodiments, for the bracket 100 for supporting the photovoltaic module 200 disposed on the north-south slope, the back tie rod 160 is provided according to the principle of setting one back tie rod 160 at an interval of three second columns 112. Since the back tie rod 160 is mainly used to enhance the stability between adjacent second columns 112, and in the bracket 100 disposed on the north-south slope, the second columns 112 are relatively stable and do not require too many back tie rods 160 to be provided.

[0064] In some other embodiments, for the bracket 100 for supporting the photovoltaic module 200 disposed on the east-west slope, the back tie rod 160 is provided according to the principle of setting one back tie rod 160 at an interval of one second column 112. Since the bracket 100 for supporting the photovoltaic module 200 disposed on the east-west slope is in an overall inclined state. Figure 8 It can be seen that the second column 112 is perpendicular to the bottom beam 130, the second column 112 is inclinedly arranged, and the connection between the second column 112 and the bottom beam 130 or the support surface 600 is subjected to a large lateral force. By providing a plurality of back tie rods 160, the stability of the second column 112 can be enhanced, thereby improving the stability of the bracket 100 as a whole.

[0065] In some embodiments, each component in the support frame body 110 can be made of U-shaped steel, which has the advantages of high strength, good stability, and light weight. U-shaped steel is easy to process and connect, and can be processed and welded in various forms, facilitating on-site construction at the construction site. This flexibility enables U-shaped steel to adapt to various complex construction environments and requirements. The cross-sectional shape of U-shaped steel is stable, not prone to deformation or with relatively small deformation, which can ensure the stability and safety of the photovoltaic module 200. Since U-shaped steel is made of relatively light material, its self-weight can be reduced, thus reducing the pressure on the roof. This feature is of great significance for the support 100 for supporting the photovoltaic module 200, which needs to reduce the self-weight of the structure or improve the bearing capacity.

[0066] The terms "first", "second", etc. are used only for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include at least one of such features, that is, include one or more of such features.

[0067] In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined. When a certain feature "includes or contains" a certain or certain features it covers, unless otherwise specifically described, this indicates that other features are not excluded and other features can be further included.
